Bathochromic azo dyes derived from 2-aminothiophenes and 2-aminothiazoles

ABSTRACT

Provided are certain bathochromic azo dyes which are prepared by reacting 2-aminothiphenes or 2-aminothiazoles, which contain a primary amino group, with 2-chloro-3-negatively-substituted maleimides. These compounds are then diazotized and coupled with azo components, for example, anilines, 1,2,3,4-tetrahydroquinolines, 2,3-dihydroindiles, and 3,4-dihydro-2H-1,4-benzoxazines to form blue-cyan azo dyes.

This is a divisional application of copending application Ser. No. 07/746,821 filed on Aug. 19, 1991, U.S. Pat. No. 5,179,207.

FIELD OF THE INVENTION

This invention belongs to the field of organic chemistry. More particularly, it relates to substituted 2-aminothiophenes, 2-aminothiazoles, and bathochromic azo colorants prepared therefrom.

BACKGROUND OF THE INVENTION

Various synthetic methods are available for preparing negatively substituted 2-aminothiophenes and 2-aminothiazoles, which are useful as intermediates for preparing azo dyes for textile fibers. (See, for example, Weaver and Shuttleworth, Dyes and Pigments, 3, 81-121 (1982).) Many of these procedures are complicated and laborious, with accompanying low yields. Often, the starting materials needed are not readily available and are expensive, thus rendering the desired negatively substituted 2-aminothiophenes and 2-aminothiazoles prohibitively expensive. Normally, to produce the most bathochromic colorants when diazotized and coupled, the 2-aminothiophenes must have negative groups in the 2,5-positions. These intermediate compounds are usually essentially colorless or are pale yellow in color as are the negatively substituted 2-aminothiazoles. Various colors from yellow to cyan can be produced by diazotizing and coupling the diazonium salts thus produced with appropriate couplers. It is very desirable to produce bathochromic blue shades and these are normally only possible when two very strongly electron withdrawing groups are in positions 2 and 5 of the intermediate thiophenes. None of these known intermediate negatively substituted 2-aminothiophenes or 2-aminothiazoles are useful as colorants.

It is known that 2-chloro-3-cyanomaleimide reacts with primary aromatic amines such as aniline to replace one of the hydrogens attached to the nitrogen, e.g. aniline reacts to give 2-anilino-3-cyanomaleimide. (Wiley et al., J. Am. Chem. Soc., 80, 138528 (1958)). ##STR1##

The compound thus produced has no significant color and has no utility as a colorant. Furthermore, since it has no primary amine present, the compound cannot be diazotized to produce a diazonium salt which is capable of being coupled to produce valuable azo colorants.

It is not expected, based on the prior art, that 2-aminothiophenes and 2-aminothiazoles, which contain primary amine groups, would react with 2-chloro-3-negatively substituted maleimides to give 5-negatively substituted 2-aminothiophenes and 2-aminothiazoles compounds useful as colorants and which have free primary amine groups capable of being diazotized to produce bathochromic azo dyes.

Various electron rich compounds are known to react with 2-chloro-3-cyanomaleimide to give colorants useful as colorants for textile fibers, but none have primary amine groups capable of being diazotized; no 2-aminothiophenes or 2-aminothiazoles are reacted. (See, for example, U.S. Pat. No. 3,096,339).

SUMMARY OF THE INVENTION

The present invention provides various substituted 2 aminothiazoles and thiophenes which are useful as intermediates in the synthesis of bathochromic azo dyes. These intermediates can then be diazotized and coupled with azo components, for example, anilines, 1,2,3,4-tetrahydroquinolines, 2,3-dihydroindoles, and 3,4-dihydro-2H-1,4-benzoxazines.

DETAILED DESCRIPTION OF THE INVENTION

The present invention provides compounds of Formula (I): ##STR2## wherein R is hydrogen, C₁ -C₈ alkyl, C₁ -C₈ substituted alkyl, C₃ -C₈ alkenyl, C₃ -C₈ alkynyl, C₅ -C₇ cycloalkyl, C₅ -C₈ substituted cycloalkyl, phenyl, or substituted phenyl;

X is cyano, C₁ -C₈ alkylsulfonyl, phenylsulfonyl, or substituted phenylsulfonyl;

Y is hydrogen, C₁ -C₄ alkyl, C₅ -C₇ cycloalkyl, halogen, phenyl, substituted phenyl, 2-thienyl, 2-thienyl substituted with one or two halogen, C₁ -C₄ alkyl, or C₁ -C₄ alkoxy, or Y is 2-furanyl;

Z is nitrogen or a group of the formula --C(R₁)═, wherein R₁ is cyano, --CO₂ R₂, --COR₃, --CONHR₂, or --SO₂ R₃, wherein R₂ is hydrogen, C₁ -C₈ alkyl, C₁ -C₈ substituted alkyl, C₅ -C₇ cycloalkyl, C₃ -C₈ alkenyl, phenyl, or substituted phenyl, and R₃ is C₁ -C₈ alkyl, phenyl, or substituted phenyl.

The utility of negatively substituted 2-amino thiazoles and 2-aminothiophenes for producing bathochromic azo dyes by diazotization and coupling of the diazonium salts thus produced with aromatic amines is known, but preparation of the intermediate amines requires complicated, laborious and expensive synthetic methods. In many cases the yields are low and multisteps synthetic routes are involved. (See, for example, John Griffiths, Colour and Constitution of Organic Molecules, Academic Press, London, 1976, p. 186; John Griffiths, editor, Development in the Chemistry and Technology of Organic Dyes, Blackwell Scientific Publications, Oxford, 1984, pages 11-13; and P. F. Gordon and P. Gregory, Organic Chemistry in Colour, Springer-Verlag, New York, 1983, page 130.)

In contrast, the negatively substituted 2-aminothiazoles and 2-aminothiophenes of this invention are prepared in high yields and in a one step reaction by reacting readily available 2-aminothiazoles and 2-aminothiophenes with maleimide compounds which contain as substitutents a reactive halogen in the 2-position and a negative groups, e.g., cyano, in the 3-position. For example, the available 2-aminothiazoles and 2-aminothiophenes of Formula (II) are reacted with 2-chloro-3-cyanomaleimide according to the following scheme: ##STR3##

Inert solvents such as esters, e.g., ethyl acetate; halogenated hydrocarbons, e.g., methylene chloride; ketones, e.g., acetone and carboxamides, e.g., N,N-dimethylformamide may be used. The reaction temperatures typically vary between room temperature and about 100° C.

In another synthetic route, (E. L. Martin et al., J. Org. Chem., 26, 2032 (1961), 2,3-dichloromaleimides are reacted with the intermediate 2-aminothiazoles and 2-aminothiophenes in the presence of metal cyanides, e.g., sodium cyanide or metal sulfinates, e.g., p-toluenesulfinic acid, Na salt to give compounds of Formula I. ##STR4##
